RETURNABLE ENVELOP.

Specification of Letters Patent.

Patented April 13, 1909.

Application filed December 16, 1907. Serial No. 406,599.

To all 'whom it may concern:

Be it known that I, TOM J. SALES, a citizen of the United States,residing at San Francisco, in the county of San Francisco and State ofCalifornia, have invented a new and useful Returnable Envelop, of whichthe following is a specification in such -full and clear terms as willenable those skilled in the art to construct and use the same.

The object of this invention is to make a return envelop for the use ofrailways, eX- press companies and the Post Oflice Department or -otherlarge businesses where it is desired to send out certain matter and havea reply to the letter sent out returned at once with the desired information.

Another object oi the invention is to make an envelop that will save thecost of one envelop and be of the same service as two where it ispossible to use the envelop for the return of matter that has been sentout in it, as in the cases mentioned above.

Another object oi' the invention is to provide means for sealing theenvelop with the smallest possible amount of the adhesive, said adhesivebeing placed on the envelo in only three places, and those places are aon the same side of the envelop blank as the same is cut'from the sheetthus making it very easy to gum.

Other objects of the invention will appear as the description proceeds.

In the drawings in which the same numeral is applied to the same partsthroughout, Figure 1 is a perspective view of the cut blank, Fig. 2 is aside elevation oi` the blank folded into an envelop, and Fig. 3 is avertical sectional view oi the envelop looking :from one end.

The envelop is formed with the body portion 1, the bottom flap 2, theend flap 3, and the securing flap 4 all the latter of which are securedto the body 1. In addition the flap 3 has a sealing flap 6 and twosecuring tabs 8 and 9, and the flap 2 has a securing flap 5 on one end.The envelop is then folded with the iiap 3 between the body portion 1and the bottom flap 2, the tabs 8 and 9 projecting through the slots inthe bottoml of the envelop. The two compartments formed in this way arethen sealed at the ends by means ofthe securing aps 4 and 5, the latterl being gummed to the body 1 and the former to the bottom flap 2.

It will be noted that the result of the above construction is to form anenvelop having two pockets with only the material necessary for one andone-half ordinary envelope. The envelop may be sealed with no more gumthan the common envelops, since there are only three gummed places. Theenvelo i is mailed in the first place, when the sealing flaps 4 and 5have been secured, by placing the letter in the compartment formed bythe bottom flap 2 and the end flap 3, the sealing flap 6 being turneddown so that its gummed side is out, the tabs 8 and 9 heilig used toseal the letter. The letter having reached its first destination thetabs are torn oil and the letter is placed in the compartment formed bythe body 1 and the end lap 3, the sealing being accomplished this timeby the use of the remaining gum on the flap 6, which is attached to thebody portion 1, since when the letter was sent out in the iirst placeonly the small amount of gum at 12 was used.

Since money is usually sent only the envelop may be used for thatpurpose when the tabs 8 and 9 are secured to the sealingI flap 6, butshould it be desired to make the envelop secure on both trips a littlemucilage may be placed on the bottom of the Ha 3 to prevent its removalfrom the envelbp, but in any event it is almost sure that the envelopwill be torn should it be tampered with.

Having thus described my invention in such full and clear terms as willenable those skilled in the art to make and use the same what I claim asnew and desire to secure by lLetters Patent ol' the United. States is asiolows:

1. In a return envelop, a body having a bottom iiap secured thereto anda slot along the line of fold oi the body and bottom liap, an end 'lapsecured to the end of the bodT and having a tab on one side and asealing flap on the other side, and tabs to secure the body to thebottom ilap at each end thereof.

2. In a return envelop, a body, an end llap having tabs on one edge anda sealing flap on the other edge, a bottom iiap secured to one of theedges of the body and having slots one way the points 11 andalongfellelne'olf'folfl ofthe bodyancl bottom ln testimony whereof I have setmy hand 'flap no registe Wizllizhe tabs on the .end flap this -7tl1rdayof December A.
